The socio-economic development and well-being of a significant part of the world’s population depends on transboundary waters, many of which are under increasing pressure from human activities and climate change. Currently, there is no systematic and scientifically-robust methodology to assess the changing conditions of five different types of transboundary water systems (transboundary groundwater; transboundary lakes/reservoirs; transboundary river basins; Large Marine Ecosystems (LMEs); and open ocean areas) that result from human activities, as well as natural and climate related events. Consequently, policy makers and international organisations are unable to be set priorities for financial resource allocation that is based upon full scientific assessment. Developing such a methodology also would facilitate the identification and assessment of positive changes in the environmental and resource situations in the transboundary water systems that result from interventions by national authorities and international/regional actors.
The Transboundary Waters Assessment Programme (TWAP) Programme will address this need by developing:
- a partnership among organisations;
- a methodology to assessment and track results for each of the five categories of transboundary water systems (transboundary groundwater; transboundary lakes/reservoirs; transboundary river basins; Large Marine Ecosystems (LMEs); and open ocean areas) under the Transboundary Waters Assessment Programme; and
- conduct a baseline transboundary waters assessment that may be conducted following completion of the MSP.
The periodic assessment will be sustained in the future through the partnership of agencies and organisations, and include data series collected by Global Environment Facility International Waters (GEF-IW) projects that would be useful to those agencies and to UNEP's GEO process.
